Correct answer: Patching the physical infrastructure that hosts the EC2 instances.
Why this is the answer
AWS operates under a shared responsibility model. For EC2 instances, AWS is responsible for the security of the cloud, which includes the underlying infrastructure. This means AWS handles patching the physical servers, networking hardware, and virtualization layer that host your EC2 instances. The customer is responsible for security in the cloud. This includes tasks like updating the guest operating system (e.g., Windows, Linux) on the EC2 instances, configuring security groups for firewall rules, and ensuring high availability for the database application itself.
